Sometimes they pan out, sometimes they don't. The one we got a few days ago hasn't. According to two highly-placed DoD sources there isn't any new startling find to disprove current assumptions.
One aspect of this seems to be recycled news. There has been a lot of talk about yellowcake uranium -- the stuff produced as the first step in refining raw ore -- in Iraq. But we found tons of it in Iraq when our forces first entered at the al-Tuwaitha site, where Saddam's nuclear weapons program was underway. Whether it was from Niger or wherever, it's indisputable that Saddam's program to develop nukes was a priority of his government. The new Iraqi government has no capability -- or desire -- to build them. But then again, there's Iran.
